.SPEGFICATON forming part of Letters Patent N o. 682,241, dated September 10, 1901.

Application filed .Tnly 5,1901. Serial No. 67,190. (No model.)

T0 all wtowt t may concern:

Beitknown that I, MANLY COOKE, a citizen of the United States, residing at Vista, in the county of Buchanan and State of Iowa, have invented a new and useful Wrench, of which the following is a specification.

This invention relates to wrenches, and has for its object to provide an improved mounting of the jaws thereof, so as to brace the same, and to arrange for the convenient adjustment of the jaws by the hand which grasps the handle of the wrench, thus requiring but one hand to adjust and operate the Wrench.

With this and other objects in View the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying dra\vings,and particularly pointed out in the appended claims, it being nnderstood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure I is a perspective view of a wrench constructed in accordance with the present invention. Fig. 2 is a cen tral longitudinal sectional view thereof. Fig. 3 is a transverse sectional view on the line 3 3 of Fig. 2.

Like characters of reference designate corresponding parts in all of the figures of the drawings.

In carrying out the invention there is pro-' vided an external handle member l, which has an outer terminal laterally-offset and longitudinally-extended jaw 2, the handle also having a longitudinal slot or bifurcation 3 extending from the shoulder 4, formed by the offset jaw, inwardly and terminated short of the opposite end of the handle. A movable handle member 5 is loosely mounted in the bifurcation of the relatively-fixed or stationary member and is pivotall'y connected theren to at its inner end, as indicated at G. The outer free end of the pivotal member is provided With an outwardly-offset and longitudinally-eXtended jaw 7, which is offset in the opposite direction from the stationary jaw and is designed to coperate therewith to grip upon a nut or other obj ect. The inner end of the jaw 7 is provided with transverse teeth 8. i

For the convenient adjustment of the movable jaw there is provided Ian externallyscrew-threaded rotatable fin ger-piece 9,which is mounted upon what will be termed the inner side of the stationary handle member and in mesh with the teeth of the movable jaw, so that by rotating the finger-piece the movablejaw maybe swung inwardly and outwardly uponits pivotalconnection with the stationary member. It will be observed that this finger-piece may be conveniently rotated by the thumb and forefinger of the hand which grasps the handle, thereby leaving the other hand free. To mount the ingerpiece, a cross-bar l0 is set into the inner edge of the stationary handle member adjacent to the inner end of the movable jaw, and a pivotpin l1 is passed through the bar, from the inner side thereof, the finger-piece being mounted upon the outer projected end of the pin, which is then upset, so as to provide an outer head 12 to hold the finger-piece against outward displacement from the pin. Y

It will be observed that the inner end portion of the inner end of the movable jaw is received within` the bifurcation in the corresponding portion of the stationary jaw, where by the inner and lighter jaw is effectually braced. Also the cross-bar which supports the finger-piece forms a stop t0 limit the outward swing of the movable member.

.1. Awrench,comprisingpivotally-connected members provided with cooperating jaws, one of the members having a rotatable externally-screw-threaded finger-piece, and the other member having a laterally-projected toothed portion in mesh with the adjusting finger-piece.

2. A wrench, comprising a bifurcated handle member, provided at its ou ter end with a laterally-offset and longitudinally-extended jaw, a movable member pivoted within the bifurcation, and having its outer free end provided with a laterally-offset and longitudinally-projected jaw, the inner end of the jaw having teeth, and an externally-screwthreaded adjusting finger -piece rotatably mounted upon the inner sid-e of the rstmentioned handle and in mesh with the teeth of the movable jaw.

3. A Wrench, comprising a stationary han- IDO die member, having its outer end provided with a laterally-offset and longitudinally-extended j aw, the handle being bifuroated from the shoulder formed by the jaw, a movable handle member pivoted within the bifurcation, with its outer free end projected outwardly through the outer end of the bifurcation and provided with a laterally-offset longitudinally-projected jaw, the innerlaterallyprojected end of the latter jaw being trans- Versely toothed, a cross-bar provided aeross the inner edge of the stationary member and l
